On a high bar, raise your body by bending your knees to your chest and go up until your back is parallel to the floor. Keeping that position, bend your arms until your legs touch the bar and extend them again to complete a repetition. For a correct technique try to keep your back always parallel to the ground and your shoulder blades retracted.
